Cricket as we all know is celebrated as a religion in India.
Over the years cricket has incorporated into the game a few of the latest technological advances available. There have been some rejections of technology, such as the use of aluminium cricket bats, but generally the ICC has been rightly cautious about making changes to the game that will impact the players and spectators. Here are some of the technologies that has been evolved in recent years.
4) Zing Wicket system.
In recent years , there are many technologies that have evolved in cricket. Involving technology in cricket has made the process of decision making more accurate.
Snickometer which determines whether the ball has touched the bat is highly essential in cricket. As most of you would have seen snickometers in televisions and would be familiar with its usage, here the actual working of snickometer is discussed. When the ball hits the bat a sound of particular frequency is produced. The stump microphone records this sound and filters it from the ambient or the surrounding noise. The sound is then visualised in an oscilloscope which measures sound waves. If the ball does not hit the bat then the snickometer graph shows a straight line else it shows a sharp spike indicating that the ball has kissed the bat.
Hotspot is another technology which is used to determine where the ball has struck the bastman's pad or bat. It enhances the accuracy of decisions being taken. It is similar to snickometer but the snickometer just gives a rise in spike when the ball touches the bat or pad. Hotspot gives clear indication whether the ball has touched the bat or pad. It is an infrared imaging system which requires 2 infrared cameras which are opposite to each other above the field of game. These camera sense and measure heat from friction generated by collision such as ball on pad, ball on bat, ground etc. It uses a subtraction technique . A series of black and white negative frames is generated and helps in localising the balls point of contact. The infrared image shows a bright spot where contact friction from the ball has elevated the local temperature.
Hawkeye is used in various sports to track the ball and display the record of the statistical path through movie image. It uses 6 or 7 cameras that track the ball from different angles. The video obtained from all the cameras are then merged together to give a 3-d vision.
Zing Bail System:
Another trending technology in cricket is the zing wicket system where the stumps will flash the moment when the ball hits them. Normally stumps are made of wood and in recent times LED lights are embedded in them.The bails are powered with low voltage batteries .They contain a microprocessor that detects when the contact between the bails and the stump has been broken. The bails are illuminated within 1/1000th of a second. They can be vibrated, rained upon but will only flash when both ends are completely dislodged.
